[CARBONDATA-3624] Support creating MV datamap without giving filter columns in projection and bug fixes

Problem:
We need to maintain a fieldRelationMap between MV and Parent tables, for inheriting properties from parent table and for restricting alter opeartions on main table columns. Deriving fieldRelationMap from logical Plan should be in a generalised way, hence adding filter columns also to projection check was required. But this check should not restrict user to create datamap, if user query doesnt contain filter columns in projection.

Solution:
Use Modular Plan instead of Logical plan to form a fieldRelationMap and make it generalised for all type's of queries. By this way, we can avoid restricting user to give filter columns in projection while creating datamap.

This closes #3517
